Description of problem:
rhc-chk cannot pass with the additional ssh key pair.

Version-Release number of selected component (if applicable):
rhc-node-0.84.23-1.el6_2.noarch 
rhc-broker-0.84.40-1.el6_2.noarch 

How reproducible:
always

Steps to Reproduce:
1.create domain with existed ssh key pair
# rhc-create-domain -n domain1 -l bmeng 
2.generate new ssh key pair and add the public key to domain above
# ssh-keygen 
# rhc-ctl-domain -a key1 -k libra_id_rsa_2.pub 
3.change the ssh key path and do rhc-chk
# vi ~/.openshift/express.config
ssh_key_file = 'libra_id_rsa_2'
# rhc-chk
  
Actual results:
rhc-chk failed due to ssh key unmatched.

Expected results:
rhc-chk should pass since the additional key pair matched.
